Young birds have white markings on the crown and white chin and throat contrasting with a dark face. Juveniles are browner and have broad white tips to the head and wing feathers. The eye-ring is gray to yellow (a feature shared with the Common Hawk-Cuckoo

In the Kangra Valley of India, the call is interpreted as the soul of the dead shepherd uttering "where is my sheep". In China, one of the names (simplified Chinese: 四声杜鹃; traditional Chinese: 四聲杜鵑; pinyin: sìshēngdùjuān) means "four-note cuckoo".

Taxonomy and systematics

Two subspecies are generally recognized. The nominate form is found in much of continental Asia, while concretus S.

Distribution and habitat

The species is found widely distributed across Asia. The preferred habitat is deciduous and evergreen forests but also occur in garden lands and thick scrub.

Some populations appear to migrate south in winter, although there are breeding populations in the southern areas as well, with specimens netted at night or recorded at lighthouses.

The eggs of the cuckoo hatch in 12 days while those of the Brown Shrike in the Amur region take 14 days. During the third of fourth day, the young bird bends its back when touched and heaves out other eggs or nestlings. This instinct is lost soon after.
